5 Claims.

This invention relates to new and useful improvements in health heat lamps.

More particularly, the present invention proposes the construction of a health heat lamp which may stay on all night or for any other prolonged period without overheating or causing injury to the occupants of the room in which it is being used and which will artificially reproduce atmospheric conditions of a desert in a defined area of a room.

Another object of the present invention proposes iorming a health heat lamp in which the ultraviolet lamp can be completely baffled in the enclosure so that the rays cannot escape and burn the patient.

Still further, the present invention proposes constructing a health heat lamp having a stand or cabinet with a filter covered inlet opening and a motor and fan to draw in air and pass it through an ultraviolet field generated by an ultraviolet lamp, which sterilizes the air, and also serves to cool the tube, the stand or cabinet being connected with a reflector having an infrared element so that the filtered sterile air will pass by the infrared element and the rays and air stream will be directed in a common path.

As a further object, the present invention proposes arranging the filter, fan, ultraviolet lamp and infrared element so as to provide clean,

dry sanitized air continually purged of aerial contaminants and especially beneficial for ill persons, such as those who suffer from sinus trouble, hay fever, asthma and upper respiratory discomforts, to induce restful sleep, particularly during the night when discomforts are most prevalent.

A still further object of the present invention proposes providing a medicant cup or container on the grill of the lamp disposed in front of the infrared heater element so that the infrared rays may help evaporate the medicant and the patient may sleep in a cone of filtered air, mildly medicated if desired, warmed and dehumidified, sterile and sanitized by ultraviolet rays without the creation of harmful nitrous oxide or ozone which is an irritant to asthmatics.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 13 is a fragmentary detail view of the clamp shown in Fig. 12 as connecting the inner and outer reflectors.

Fig. 14 is a top plan view of the infrared element.

The health heat lamp has a hollow stand or cabinet l5 shown tubular in shape. It may be made of metal or any other material adapted for such use. The stand [5 has a base l6 adapted to support the stand in upright position.

An ultraviolet, ultra high frequency germicidal lamp ll is mounted in the stand l5, brackets l8 and is being secured to the stand to hold the lamp H and for electrical connections to it. A suitable ballast, such as forty watt ballast 2E5 is provided for the lamp I? in the base It, the ballast being removably secured to the base.

The base 5 has an opening 2| (Fig. 2) into the stand Hi, the opening 2| being substantially the same size as the inside diameter of the stand. A filter 22 of fiberglass or the like is removably secured over the opening 2'! to filter out dust and other foreign particles from air passing through the opening 2|.

An outer reflector 23 is pivotally mounted on the stand id at the top of the stand. An opening 24 is formed in the reflector and a duct 25 connects the hollow stand with the reflector, duct 25 having an opening 26 (Fig. 2) aligning with open-- ing 24 in the reflector. A clamping screw knob 21 engages a threaded stud 28 on the reflector and a slot 29 is provided in the rear side of duct for the stud to pass through so that the screw knob 21 may engage it and bear against the rear side of the duct bridging the slot 29. In this manner, the reflector 23 may be tilted to various angles and secured at those angles. A twenty degree movement, however, has been found to be ample. Protective guard members 30 (Fig. 1) are provided at the face of the reflector.

An infrared or black heat element 3 I is mounted in the reflector to produce invisible, nonactinic radiant energy detectable by its thermal effect. Element 3! consists of a stainless steel sheathing 32 (Fig. 3) over a ceramic liner 33 enclosing a helical coil 34 of Nichrome wire. When hot, the element 3i is nonincandescent and emits rays having wave lengths longer than those of visible light and shorter than those of radio waves, the waves emitted being longer than 7600 Angstroms or angstrom units. The element 3! is mounted in an inner reflector 23 by strip brackets 35 which are removably secured to the reflectors, as by screws 3% (see Fig. 2). The space between the two reflectors permits air passage out the front of the reflector 23 in a substantially annular or cone shaped air stream.

A motor ill is mounted by strap 38 in the casing near the base above the filter 22 and base open- 2i and a fan 39 is secured to the motor shaft to draw air through the filter and base opening and force it up through the stand over the ultraviolet lamp ll and out duct opening 25 to the reflector 23 where it can be directed by the reflector in any direction desired along with the infrared rays and the sterilized air rays from the element 3i and lamp 1?.

A. master switch it (Fig. 2) is provided on the duct 25 to connect and disconnect the entire unit to and from a source of electrical energy (not shown). A switch 4! is also provided for the infrared element 31 and a switch 42 for the ultraviolet and ultra high frequency lamp ll. Motor switch 33 for the motor 37 completes the bank of switch. All switches are connected with their respective units and with the source of electrical energy.

The forced air drawn in the stand or cabinet by the fan 39 and directed over the ultraviolet germicidal lamp it serves to cool the lamp and can be regulated by proper fan speed to keep the lamp at the temperature at which the lamp operates at maximum emciency. Commercially available tubes operating at a 70 maximum efficiency temperature can be used in the health lamp of the present invention with their best results. The ultra, high frequency and the ultraviolet waves will destroy bacteria, germs and other harmful microorganisms which get through the filter 22.

Preferably, ultraviolet lamp [l is one adapted to emit radiant (nonluminous) energy in waves centering around the rang of from 3000 down to 1850 Angstroms or angstrom units and one which produces little or no ozone. The inside of the stand of cabinet i5 adjacent the lamp l! is sprayed with a specular aluminum lining for a high reflection factor and intensification of the rays.

A medicant or deodorant holding cup 44 may be removably secured to the center of grill members Eli? as shown in the first three figures. Preferably the cup is of copper for ready heat evaporation 4 of the contents by the infrared heater to disperse the contents into the air stream.

Fig. 1 shows the lamp as used at night on a patient alongside of bed 46.
